Antioxidants are chemical compounds that help protect the body from the harmful effects of oxidative stress. Oxidative stress occurs when the body's cells produce free radicals that can lead to cell damage and contribute to ageing and the development of various diseases, including cancer and cardiovascular disease. Antioxidants neutralize these free radicals by donating electrons, thus preventing potential damage.
Foods rich in antioxidants include fruits, vegetables, nuts, seeds and whole grains. Some well-known antioxidants include vitamins such as C and E, minerals such as selenium, as well as plant substances such as flavonoids and carotenoids. Consuming a varied diet with a sufficient amount of antioxidant-rich foods is considered beneficial for maintaining cell health and reducing the risk of chronic diseases. At the same time, it is important to remember that dietary balance is key, as excessive intake of antioxidants through supplements does not necessarily provide health benefits and can even be harmful.
